FOLDING AND BINDING ATTACHMENT FOR SEW|NG=MACHINES.

SPECIFICATION forming part of Letters Patent No. 273,890, dated March13, 1883,

Application filed December 23,1882.

To all whom it may concern:

Be it known that 1, WILLIAM PRETTY, Jr., of Ipswich, in the-county ofSuffolk, England, have invented an Improved Folding Device for Binders,of which the following is a specification.

My invention has for its object to fold over the edges of a strip offabric, to adapt itto be folded over the edge of another fabric to forma bindingwith turned-in or finished edges, and this I effect by the useof the device hereinafter described.

My invention consists in the combination of said device and appliancesconstructed and adapted to be-applied to a sewing-machine in suchposition that the binding can be mechanically applied to and sewed inits place on the fabric to be bound.

In the drawings, Figure l is a perspective view of the improved device.Fig. 2 is a plan illustrating the application of the device to thesewing-machine in the act of binding. Fig. 3 is a view illustrating theform taken by the binding-strip as it is being folded and applied to thefabric. Fig. 4 is a perspective view of the device which folds the stripjust prior to its application to the fabric. Fig. 5 is a rear view ofsaid portion. Fig. 6 is a section on line 1 2, Fig. l.

The folding device consists of a plate with its edges bent over to forma flat back,b, contracting in width toward one end, two edge flanges, cc, bent down nearly upon the back, and two iii-flanges, 66. A loosewedge-shaped tongue, D, is introduced between the flanges e and the backof the plate 0, as shown, and the strip a: of binding material iscarried between the tongue and the back I), the gradual contraction andconformation of the channel through which it passes causing the edges tobe turned over gradually until they are brought flat upon the face ofthe body of the strip as it emerges from the device. The tongue D, bykeeping the strip flat upon the back I), prevents the strip from foldingor wrinkling at the middle, and insures the even and regular turningover of the edges, and, being removable, facilitates the insertion andadjustment of the strip. Vertical guide-rods a aserve to hold the strip(No model.)

in a vertical position, so that it properly euters the folder.

The edge-turning device thus constructed may be used alone for differentpurposesas, for instance, for forming bindings from strips, the rawedges of which are turned in, and may be sewed, cemented, or pasted downupon the body.

The strip, with its edges folded down,may be reeled or rolled forsubsequent application as a binding, by hand, or it may be conductedfrom the folder and applied directly to a fab ric by a binding device,B. This binder consists of asemi-cylindrical case havinga curved slot,2', extending through it longitudinally, and a notch,n,in the front end,the front outer edge of the case being cut oil upon a plane crossing theline of the slot t at an angle of about forty-five degrees. Owing to thecurved form of the slot i, the strip of fabric conducted through saidslot is thrown back at the folded edges and forward at the center, sothat when the strip is carried at right angles through the notch. 12 thefolded edges will bebrought upon each other or upon the edge of thefabric Y, also passed through the slot and lying between said edges.

The folder and binder are arranged upon a base, 0, forming one device,so constructed that it may be applied to the bed of a sewingmachine, andthe strip is first folded, then carried to the binder, and then carriedat right angles from the latter and extended beneath the presser-footand the feeding device, so that the binding-strip and the sheet offabric to whichit is applied will both be fed together beneath theneedle, by which the binding will be sewed to the fabric.

I claim- 1. A device for folding down the edges of strips of fabric,consisting of a flat plate grad= ually contracted from one end to theother, with the edges turned down and in to form flanges c e, and aremovable fiat tongue, D, parallel to the plate, and fitting between theflanges and the plate, substantially as set forth.

2. The combination of the folding device A, constructed to fold down theedges of a strip of fabric npon the body thereof, and a In testimonywhereofI havesigned my name binder, B, having a curved channel, wherebyto this specification in the presenceof two subsaid strip is curvedlongitudinally, and an scribing witnesses. end notch at right angles tosaid channel, through which the strip may be doubled and drawn at rightangles to the channel, substantially as set forth.
